#include <cmath>
#include <math.h>
using namespace std;

int main()
{
double x = 1;
double som = 0;
double lim_nbr = pow(10.0, -6);
int n = 1;
do{
x = n / pow((4 * pow(n, 2)- 1 ),2);
som += x;
n+=1;
}while (x >= lim_nbr);
double correctSum = 1/8.0 ;
cout << "Sum = " << som << endl;
cout << "Sumcorrect = " << correctSum << endl;

return 0;
}

Answer 7

Where I have X>=lim_nbr I must also do for X<=lim_nbr.

Answer 8

but the result I had is good just a small modification in the code.

Answer 9

It's urgent

Answer 10

where do i put this code?

Answer 11

the result in this code must remain the same, despite adding something

in the condition X>=lim_nbr I must also make a condition for X<lim_nbr.

Answer 13

in fact I do not understand why the teacher asks me this because the result is good

Answer 14

I don't know much about C++ I don't know how to use it 😅

Answer 15
